Capture radio button selection as input for Find

I have a button for a script that takes the user to a layout (for use on iOS or macOS) that presents a value list as 100 radio buttons in a second layout. I want the numerical value of the radio button (1-100) in that second layout to be used as the value for a Find that will take the user to that record number in the original layout. It would accomplish the same thing as a Find where the user would type a value from 1-100 into the field but be mouse/touch based. I am not too with variables (concept but not syntax). Is the radio button value already stored, or does it need to be captured? FM 19 on Sonoma.
